Uhh .. and thats about it :). Build/Deploy, add these two WebParts, and set the WebPartManager in Connect DisplayMode. You should see connect menu items appear by each Webpart as shown below.

Click on "Connect" on either, I am going to click on the Connect Verb for the OPML Editor. This should pop open a ConnectionsZone as shown below.

Click on "Create a connection to a provider." Choose "RssImport", and click "Connect".

Click "Close", set the page in Browse display mode.

Bingo, you have at your hands an RSS Reader, just like Bloglines or Newsgator. NEAT !! :-). This can be seen in action below -

Now as an exercise for you, do the same on a WebPage with two WebPartZones, in two columns - the left column being the thinner one holds the OPML Editor, and vice versa.

I am going to skip Atlas/Ajax integration until the very end, depending upon the interest from the audience :-). Next, I will use these webparts we just wrote, and create an RSS Reader in Sharepoint 2007.

Stay tuned.

Thou shalt -

Sound off but keep it civil:

Did you ever get around to writing this bit as I am just in the process of trying to link some web parts and have them communicate between each other using AJAX (without using smart web part) and was looking for ideas as to how I might approach it.
